To be able to identify these and other minerals, we need to look at the properties used to separate and distinguish these minerals.

 Naturally occuring  Solid  Formed by inorganic processes  Have a crystal structure  Definite chemical composition  To be a mineral – MUST HAVE.

Properties 1.Cleavage: the way some minerals break along certain lines of weakness in their structure - Click for animation

Properties 2.Fracture describe the shape and texture of the surface formed when a mineral is fractured - Click for animation

Properties 3.Hardness: measures how well a substance resists scratching fingernail = 2.5 copper coin = 4.5 iron nail = 5.5 glass = 6 -

Properties 4.Streak colour of powdered mineral observed on a streak plate (or tile) * restriction: mineral must have a hardness of <7 (tile hardness is 7) to leave a mark - Click for animation

Properties 5.Lustre: appearance/reflection of light from the surface Vitreous (glassy) Metallic Pearly/silky -

Properties 5.Density mass per unit volume (g/mL); depends on the elements that make up the mineral -

Identification 7.Magnetism: deflecting a compass needle due to the presence of iron 8.Crystal Shape: tendency of minerals to develop certain shapes -
